DCMT 070204 T9225 ISO turning insert by Tungaloy — rhombic 07, 7° relief

A DCMT070204 T9225 indexable turning insert designed for medium to heavy steel turning, offering a robust CVD‑coated carbide grade for interrupted cuts and variable engagement.

• CVD-coated carbide grade T9225
• Robust universal grade for steel turning
• Rhombic 07 geometry with 7° relief
• 0.4 mm corner radius, single-sided chipbreaker

Consistent performance under variable cutting conditions

The combination of a CVD-coated surface and a tough carbide substrate provides enhanced resistance to abrasive wear while retaining sufficient toughness for interrupted machining. This makes the insert particularly suitable for medium to heavy steel turning, where engagement conditions can change rapidly. The protective coating reduces flank wear and helps maintain cutting-edge integrity, which in turn preserves component tolerances and extends effective tool life.

Geometry that balances strength and surface finish

The rhombic 07 geometry with a 0.4 mm corner radius delivers an effective balance between strength for roughing and edge definition for semi‑finishing. A 7° relief reduces rubbing on the flank face and improves chip flow consistency, while the single-sided chipbreaker controls swarf formation in a variety of feed ranges. These geometric choices translate into fewer insert changes and more predictable surface quality on turned parts.

Secure clamping and ISO compatibility for efficient tool management

The insert is ISO‑standardised and features a cylindrical hole with a one-sided countersink (40°–60°) for reliable location and clamping. Compatibility with holders is determined by form, relief, tolerance class, fastening method, size and thickness; selecting the correct holder, shim and clamp ensures repeatable seating and torque transmission. The standardised format simplifies inventory and tool planning in mixed‑model production environments.

Application guidance and system benefits

Designed primarily for external and internal turning, this insert is a practical choice when machining steels with intermittent cuts or where slightly varying engagement demands extra edge toughness. The recommended system comprises the ISO insert, a suitable external holder or boring bar, a backing shim or clamp kit and replacement screws; assembling these elements correctly reduces the risk of misalignment and improves process stability. For converters and workshop managers, the predictable behaviour of the grade reduces scrappage and supports consistent throughput.

FAQ

What materials is this insert intended for?
The DCMT070204 T9225 insert is formulated for medium to heavy steel turning and performs well where interrupted cuts or variable engagement require extra toughness.

How does the T9225 grade affect tool life?
The T9225 CVD‑coated carbide offers enhanced wear resistance combined with toughness, which tends to extend effective tool life under mixed cutting conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, relief, tolerance class, fastening method, size and thickness; use holders specified for ISO DCMT inserts and ensure matching shims and clamp kits.

Can this insert be used for internal turning?
Yes, the ISO configuration of the DCMT070204 makes it suitable for both external and internal turning when mounted in an appropriate boring bar or holder.

What edge preparation and chip control does it provide?
The 0.4 mm corner radius and single‑sided chipbreaker optimise chip formation and improve surface finish while providing edge strength for heavier cuts.
